Hang loading omap_rng on MacchiatoBin with 4.15-rc7

Hi,

Loading omap_rng module on McBin causes hangup (in about 9/10 times).
Looking at /proc/interrupts it seems the interrupt starts running like
crazy, and after a while the whole system is unresponsive. This with
Debian kernel (everything possible as modules) and EFI as bootloader.
The EFI firmware appears[1] to use the rng unit to provide a seed for
KASRL, I wonder if the driver needs to depend less on the state left
by firmware, or the firmware needs to de-initialize the RNG before
booting.
